Di750 Error Code SC28-01

[Printhead]

Hello everyone, I have a Di750 with error code SC28-01 can tell where to look to fix this code? Thanks

28-01 The charging on/off operation has been performed five consecutive times since the charging trouble detection signal was detected at start of charging. (I can't stand the wording in some Minolta manuals!) I would check/clean the main charge. There is also a tech pub for 28-01 and gray copies. Clean toner control sensor board or replace it. 56AA-9100

Where do I find the main charge? Where is the toner sensor? Thanks mtech

Does the toner charging unit slide out behing the toner bottle?

[mtech]

The main charge is located on the top of the drum unit and the sensor is located in the drum unit as well. The whole drum unit slides out from the front. You need to remove the brown cover and the unit is in back of that. Best of luck, be careful not to damage the drum when you get the unit out.
